Atoms and ions are brought to life in Salts a fully interactive atomistic simulation that reveals the motions of atoms and ions as they interact to form beautiful crystals. Discover the physics behind the structures and properties of these minerals, and explore the effects of charge and ionic radii on melting points, bond strength, and crystal lattices. Enjoy the atoms (and the ions)

WebMO: Molecule Editor, Viewer, and Computational Chemistry Interface

WebMO allows users to build and view molecules in 3-D, visualize orbitals and symmetry elements, lookup chemical information and properties from external databases, and access state-of-the-art computational chemistry programs. WebMO is recommended for students and faculty in high school, college, and graduate school who desire mobile access to molecular structures, information, and calculations. WebMO capabilities include:- Build molecules by drawing atoms and bonds in a 3-D molecular editor, or by speaking the name (e.g., aspirin)- Optimize structures using VSEPR theory or molecular mechanics- View Huckel molecular orbitals, electron density, and electrostatic potential- View point group and symmetry elements of molecules- Lookup basic molecular information, including IUPAC and common names, stoichiometry, molar mass- Lookup chemical data from PubChem and ChemSpider- Lookup experimental and predicted molecular properties from external databases (NIST, Sigma-Aldrich)- Lookup IR, UV-VIS, NMR, and mass spectra from external databases (NIST, SDBS)- Capture high-resolution molecular images- Save and recall molecular structures locally- Export and import structures via emailWebMO is also a front-end to WebMO servers (version 14 and higher):- Supports Gaussian, GAMESS, Molpro, MOPAC, NWChem, ORCA, PQS, PSI, Quantum Espresso, VASP, Q-Chem, and Tinker computational chemistry programs- Submit, monitor, and view calculations- View formatted tabular data extracted from output files, as well as raw output- Visualize geometry, partial charges, dipole moment, normal vibrational modes, molecular orbitals, and NMR/IR/UV-VIS spectra

Hydrogen!

Hydrogen is an iOS app dedicated to the visualization of the atomic orbitals of the hydrogen atom as described by quantum mechanics. It is designed to be a tool for teachers and students who are already familiar with some quantum mechanical concepts, but anyone may appreciate the beauty of quantum mechanics :)So, what does an atom look like? INFO MENU: you may read informations about how to use Hydrogen , learn more about the quantum mechanics behind it, what you can actually see and what you should look for
